Description

qrbackup is a utility for printing files onto paper using QR codes. Restoring the data does not need any special software and is easily done using one of the many decoders available (e.g. ZBar).

The man page includes examples on how to backup SSH authentication keys and GnuPG cryptography keys.

While qrbackup is predestined for creating backups of cryptography keys, no steps are taken to encrypt or obfuscate the data. Necessary precautions should be taken for the secure storage of the printed paper.
